To resolve a system lockout, turn off the power to the furnace for about 10 minutes then the board should reset.

As for the green wires, how did they come loose? Where do they come from (thermostat) ? If at the air handler tell us all the terminals on the control board that DO have wires connected... use the letter designation for each terminal like G, R, C etc.

thank you. but i still have the wire issues. i don't know where they came from. i believe one is the ground wire but i'm not sure where it needs to be grounded to. The other comes from the heater compartment (that is a green and yellow wire) and i don't know where this one goes to.
